There presently exist a wide variety of techniques for collection oftrash, waste material and other refuse. One of the most widespreadtechniques consists of mobile units, normally operated by the SanitationDepartment of a city, township or other municipality. The mo bile unitsare provided with large volume storage means for receiving refuse. Themobile units travel along the streets of the municipality. Usually oneindividual in addition to the driver of the mobile unit walks to therefuse cans left by the roadside, lifts the refuse container anddeposits its contents into the refuse storage means. In certainapplications the refuse is compacted to increase the storage capacity ofthe mobile units.

The present invention is characterized by providing a system notheretofore employed for the collection of waste material from wastecontainers and is comprised of a mobile unit having a vacuum generatingsource and an elongated flexible hose coupled thereto. The hose ismounted upon the mobile unit in such a way as to be simply and readilymovable so as to be positioned over and upon a refuse container. Themobile unit is provided with compacting means to enhance the storagecapability of the mobile unit.

The free end of the vacuum hose is provided, in one embodiment, with acircular flange spaced inwardly from said free end and adapted to beseated upon the upper open end of a refuse container. The surface of theflange engaging the open end of the refuse container is preferablyformed of a flexible resilient material so as to generally conform tothe contour of the upper lip of the refuse container. The remainingmarginal portion of the free end extending beyond the flange protrudesinto the interior of the refuse container. One alternative embodimentemploys a serrated flange portion. As a further alternative, the flangemay be omitted.

The refuse container is provided with an opening near its bottom(closed) end so as to provide a continuous path for the flow of air.Suitable means are provided for preventing blockage of the opening inthe refuse container so as to expedite the flow of air therethrough. Themethod and apparatus of the present invention greatly facilitates thehandling and disposal of refuse by eliminating the need for transport ofa refuse container to the storage bin of the mobile unit, requiring onlythat the lid, if any, of the refuse container be removed and that thevacuum hose be placed over and upon the refuse container so as towithdraw its contents by the vacuum generating means.

The opening in the refuse container is preferably located so as toprevent any liquid collected in the bottom of the refuse container fromspilling out and further so as to prevent any liquid collected withinthe bottom of the container or any other refuse for that matter, fromblocking the inlet opening so as to impair the operation of the vacuumhose in the withdrawal of refuse.

It is, therefore, one object of the present invention to provide a novelmethod and apparatus for extracting and collecting refuse from refusecontainers and the like wherein refuse is collected directly from arefuse container by means of a vacuum hose fitted over and upon therefuse container and being coupled through vacuum generating means tothe refuse storage means of a mobile unit.

Another object of the present invention is to provide a novel method forthe collection of refuse comprising the steps of coupling a refusecontainer to a mobile refuse storage means having a vacuum generatingmeans, through a vacuum collection hose, all of which means are mountedupon a mobile unit, positioning the free end of the vacuum hose over andupon a refuse container and thereby extracting refuse from saidcontainer.

Still another object of the present invention is to provide a novelmethod and apparatus for simply and rapidly withdrawing and collectingrefuse from containers and the like wherein the container is providedwith inlet opening means suitable for expediting the withdrawal ofrefuse from the container and through hose means unter the control of avacuum source.

Still another object of the present invention is to provide a novelmethod and apparatus for simply and rapidly withdrawing and collectingrefuse from containers and the like wherein the container is providedwith inlet opening means suitable for expediting the withdrawal ofrefuse from the container and through hose means under the control of avacuum source and whereby said vacuum hose means is adapted to have itsfree end fitted within the open end of said refuse container so as togenerally conform to said open end whereby the refuse within thecontainer is rapidly extracted therefrom under the vacuum conditioncreated by the vacuum generating means.

Still another object of the present invention is to provide a novelrefuse container for use in facilitating extraction of the contents ofsaid container by a vacuum technique wherein an opening is provided nearthe bottom of said refuse container and further means are provided forsubstantially preventing the temporary or permanent sealing of saidopening so that the vacuum operation will not be impaired duringextraction of the contents of the refuse container.

These as well as other objects of the present invention will becomeapparent when reading the accompanying description and drawings inwhich:

FIG. 1 is a perspective view showing a mobile unit for collecting refuseand embodying the principles of the present invention.

FIG. la shows a plan view of the compactor of FIG. I in greater detail.

FIG. 2 is a sectional view of the vacuum suction hose of FIG. 1 showingthe structure of the free end thereof in detail.

FIG. 2a is a side view of an alternative embodiment of the hose ofFIG.2.

FIGS. 2b and 2c are side views, partially sectionalized, of otheralternative embodiments of the hose of FIG. 2.

FIGS. 3 through 7b are views showing a plurality of embodiments ofrefuse containers incorporating the principles of the present inventionand adapted to be advantageously used with the mobile unit of FIG. 1.

Referring now to the drawings, FIG. 1 shows a perspective view of amobile unit typically having a cab 11 for housing the driver. Cab 11 istypically further provided with appropriate controls (not shown forpurposes of simplicity) for operating the refuse collector equipment.The rearward end of the vehicle 10 is provided with a storage bodyportion 12 for receiving the collected refuse. A high pressure blower 13is mounted between the storage container 12 and cab 11 and maypreferably be driven by an auxiliary internal combustion engine 14.Blower 13 is coupled by duct means 15 to the storage portion 12 toestablish a vacuum or negative pressure condition which is furthercoupled to flexible hose 16 which communicates with the storagecontainer 12 by means of an inlet opening 17.

A hose supporting linkage assembly 18 is provided and may be comprisedof a first elongated arm 19 pivotally mounted at 20 to the top wall ofcontainer 12 which arm supports and guides supporting ropes 21 and 21a.Bracing means maintain sufficient tension on the support ropes toreleasably hold hose 16 in position.

Support rope assembly 21 has its free ends connected to straps 26a and26b which surround hose 16. A similar strap 27 embraces hose 16 in asimilar fashion and is secured to the free ends of rope assembly 210. Aguiding ring 270, joined to brace 27 is provided for guiding the hoseover a refuse container.

The linkage assembly comprised substantially of components 19, 20, 21and 21a, is provided for moving the free end of the vacuum hose assembly16 either upwardly or downwardly, as shown by arrows A and Brespectively, as well as moving the hose free end in the horizontaldirection, so as to position the free end of the vacuum hose immediatelyabove and upon a refuse container, in a manner to be more fullydescribed.

The flexible vacuum hose is preferably of a corrugated hose type whichgreatly facilitates positioning of the hose to perform a refuse removaland storage operation.

As is well known in the refuse collection art, suitable means isprovided for drawing air through vacuum hose 16 and storage container12, while providing means 28 for preventing the passage of the refusematerial from storage container 12, the upper portion of storagecontainer l2 and through duct 15 and into the blower mechanism 13. Theoutput of blower 13 passes through dust trap DT to the atmosphere.Arrows C indicate the flow of air through the system. Screen S permitssome of the air entering storage container 12 to pass into theatmosphere.

A compactor assembly 29 is positioned beneath the outlet end 16b ofvacuum hose assembly 16 to drop the collected refuse into the mobilestorage container 12. Assembly 29 comprises a pair of rotatable gates101a and 10th pivoted about suitable operating mechanisms 102a and 102b,respectively. The gates are movable between the solid line positions andthe dotted line positions 101a and 101b', respectively. A pistonoperated plate 103 is movable between the solid line position as shownand the dotted line position 102' by suitable piston drive means 103 and104. ln actuality, the piston drive means may comprise a pair of upperpiston drive means 103,103 which may be secured to the upper corners102, and a pair of lower piston drive means 104,104 which may be coupledto the lower corners of plate 102. The piston drive means may beoperated from cab 11 by suitable controls (not shown). In operation,gates 101a and 10) (which may also be controlled from cab 11) occupy thesolid line position and plate 102 occupies the solid line position. Therefuse passes through vacuum hose 16 and is deposited in the regionbetween gates 1010-1011: and plate 102. The control actuating the pistondrive means 103 and 104 then moves plate 102 in the direction shown byarrow D to compact the refuse between plate 102 and gates 101a 101b. Theplate 102 is then moved in the direction of arrow E to return to itssolid line position, or alternatively remains in position 102'. Gates101a and 101!) are then rotated to their dotted line positions 101a and101b' and the piston drive means 103 and 104 are then operated to moveplate 102 to the dotted line position 102" so as to push the refuse pastthe free ends of open gates 101a and 1011:. Plate 102 is then moved inthe direction shown by arrow E to return to the solid line position 102and, thereafter, gates 101a and 10: are returned to their solid lineposition. The gates are free to move to their solid line positionwithout touching the refuse as a result of the fact that plate 102 hasmoved beyond the free ends so as to move the compacted refuse away fromthe path of movement of the gates as they rotate from the dotted linepositions 101a'-l01b' to the solid line positions 1010-1011:. Thecompactor need not be operated after collection of each individual trashcan but may be made sufficient in size so as to compact refuse collectedfrom a number of individual refuse containers.

FIG. 2 shows a portion of a flexible hose arrangement employed in thepresent invention, which portion represents the free end portion of thehose 16 of F K]. 1. As shown therein, the hose 16 shows a corrugated endportion thereof 30 having a carcass portion generally indicated at 31,being formed of a selected elastomeric material such as natural orsynthetic rubber, with suitable fabric metal reenforcing imbeddedtherein, in a manner known in the art. A flange portion, generallyindicated at 32 is disposed at, and integral with the free end ofcarcass portion 31.

Carcass portion 31 may be formed on a suitable mandrel, in a knownmanner, with the elastomeric body portion 33 having the usual fabricreenforcing, indicated at 34, imbedded therein.

In addition, a wire helix 35 is provided in each convolusion of thecorrugated portion to supply further reenforcement. The reenforcing wirehelix may extend over the entire length of hose or may extend away fromflange portion 32 by a suitable predetermined distance toward the right.The portion 34a of fabric reenforcement 34 is disposed adjacent theinner surface 36. The remaining portion 34b of the fabric reenforcementimbedded in carcass portion 31 lies between a second wire helix 37 andfabric layer portion 340.

The flange portion 32, is formed by the use of suitable molds, whichwill produce a substantially flat annular end surface 38 extendingoutwardly and at right angles to the longitudinal axis of the hose. Theannular outer surface 39 is concentric with the longitudinal axis of thehose. The front surface 40, which is bevelled, tapers from thecylindrical projecting portion 50 toward annular surface 42 which is ajuncture of the bevelled surface 40 and the outer annular surface 39.

The flange portion 32 includes a novel reinforcing structure which isfurther comprised of a ring shaped metallic member 43 preferably formedof a gauge galvanized sheet or other suitable metal or metal alloy or asuitable plastic. Member 43 is of right angle crosssection as is clearlyshown in the sectional view of FIG. 2 with one annular arm portion 44being disposed inwardly of and parallel to flange surface portion 38,with the other annular arm portion 45 being adjacent to and concentricwith the inner flange surface portion 36a. The outer end 46 of armportion 45 extends beyond bevelled surface 40 and into the cylindricalshaped projecting portion 50, to thereby reinforce cylindrical portion50.

A plurality of concentric layers of rubber impregnated fabrics such ascotton duck, indicated at 47, are wrapped around a portion of thecylindrical shaped section 45 and is built up to a height substantiallyequal to the height of arm 44. The forwardly extending (i.e., innermost)portion 340 of fabric reenforcing 34 are wrapped about member 43 so asto substantially encircle the innermost portion of the cylindrical ring.In addition, such reenforcement is materially augmented by cord fabricreenforcing, including longitudinally extending, high tensile strands offilaments of cotton, nylon or the like. Such cord fabric reenforcing,generally indicated at 48, comprises a portion 49 disposed in carcassportion 31 adjacent inner surface 36 thereof, a portion 49a, also incarcass portion 31 lying between wire helix 37 and cord portion 49 (andpreferably upon fabric portion 340,) and a portion 49b wrapped about andencircling the arm portions 44 and 45 of member 43, as well asencircling the portion 340 of reenforcing fabric 34.

As a procedural manner, the wire helix portion 37 is applied after thereenforcing fabric 34 and cord fabric 49 are laid down, enabling thewire helix portion 37 to provide excellent anchorage for the fabrics 34and 49 and the ring 43.

A plurality of annular-shaped layers 57 of a rubber impregnated fabricsuch as cotton duck are placed within the rubber forming flange 32 andpositioned between the left-hand end surfaces of layers 47 and thereenforcin g fabric layers 34 and 49. Reenforcing fabric portion 34c andcord portion 49b surround the layers 57 which prevent the rubber inflange 32 lying between layers 57 and tapered face 40 from becomingpermanently set and further, prevent the cutting of the rubber from face40. The layers further act as a fabric cushion" to significantlyincrease the springiness of the face 40.

The rubber portion forming face 40 is preferably of a pure gum rubberhaving a high resiliency, which characteristic enables the tapered face40 to generally conform to the uppermost edge E of a refuse container C,only a portion of which is shown in H0. 2 for purposes of simplicity.

The cylindrical portion 45 of the metallic ring 43 extends into thecylindrical shaped projecting portion 50 which, in turn, extends to asmall amount into the interior of the refuse container.

When pressure is exerted against flange portion 40 by positioning thevacuum hose in a manner shown in FIG. 2 relative to the refusecontainer, such pressure is transmitted substantially across the entireface of arm 44 by way of ring-shaped member 43. The surface pressure isthen concentrated in the immediate region of lip B, so as to compresssurface 40 and to conform to the upper lip or edge E of the refusecontainer to provide a temporary and yet high-pressure resistance seal,with the bevelled seal surface 40 facilitating the build-up of thesealing effect between sealing surfaces.

The cord fabric utilized may preferably employ about 30 cords per inchin the warp" direction (which is parallel to the central axis of thehose) and two to three cords per inch in the fill" direction (which isconcentric to the longitudinal axis of the hose).

The cord fabric reenforcement 48 is highly effective in affordingsubstantially increased axial strength for hose 16 to withstand severeend pull, since its unidirectional characteristic yields a tensilestrength of the order of 950 lbs. (in the warp" direction), with muchless bulk than that of hose duck, and provides significantly improvedanchoring strength due to the wire helix portion 37 which is wrappedaround portions 34a-34 and 49-49a of fabric 34 and cord 49,respectively.

P10. 20 shows an alternative arrangement 16' for the hose of FIG. 2wherein the projecting portion 50 is serrated at to allow debris to besucked into the vacuum hose at the sides, as shown by arrows A, as wellas at the bottom of the free end, and to avoid creation of an absolutevacuum in the vacuum hose in cases where the free end is totallyimmersed in the debris. As another added feature, in cases where thefree end of the vacuum hose is positioned upon a refuse container Cwhich is completely filled with debris, it may not be possible to pressthe free end of the vacuum hose into the container so as to have thetapered flange portion 111 bear against the upper edge E of the refusecontainer, the serrated portions 110 provide for a flow of air in orderto initiate the movement of refuse into and through the vacuum hose 16.

FIGS. 2b and 2c show still other alternative embodiments [6" and 16" ofthe vacuum hose in which the projecting cylindrical flange portion hasbeen omitted. In the embodiment of FIG. 2b, surface 40 of flange 32 issubstantially flat, whereas in the embodiment of FIG. 2c, the bevelledsurface 40 is substantially similar to that shown in FIGS. 2 and 2a. Theremaining structure of the free ends of hoses l6" and 16' issubstantially the same as that shown in FIG. 2 except that the metallicL-shaped member has a cylindrical portion 43' which is substantiallyshorter in length than the member 43 of FIG. 2 (Le, the projectingportion 45 shown in H6. 2 is omitted in the embodiments of FIGS. 2b and2c). The flange surfaces 40 of the embodiments l6, l6" and 16",respectively, are made of a gum rubber of sufficient resiliency so as toconform to the upper edge of the refuse containers upon which they arepositioned.

The successful operation of the waste removal and collection systemdepends upon an adequate flow of air through the waste container whichmay be obtained through the use of the embodiments as will be describedhereinbelow:

FIG. 3 shows one arrangement for waste container C which is typically ofgenerally circular shape, having slightly tapered side walls 61 and acircular shaped bottom or floor 62. Since refuse containers of this typeare adapted to receive any form of refuse, it is typically preferredthat the refuse container be of a leak-proof structure to prevent theleakage of any fluid which may be collected at the bottom of thecontainer upon the floor or storage area in which the container islocated. FIG. 3 shows two suitable arrangements, only one of which needbe provided in any refuse container. The left-hand arrangement 63 iscomprised of an opening 64 provided along the side wall a spaceddistance above the base 62 of the container. Since refuse is quite oftenplaced in a refuse container and compacted to a certain degree, it isimportant to provide means for preventing the blockage of opening 64 topermit the passage of air therethrough. This is accomplished by means ofa plate 65 whose diagonally aligned edges 65a and 65b are preferablywelded along the interior surface of the container side wall 61. Thelower edge 65c of plate 65 is positioned a spaced distance above thebase 62 of the container so as to permit free passage of air enteringopening and passing beneath edge 65 in the manner shown by arrows 66(see FIG. 3a). The right-hand embodiment 63' of FIG. 3 is substantiallyidentical to the left-hand embodiment 63 except that plate 65' is shownas being arranged at a greater inclined angle. It should be understoodthat only one such embodiment need be provided in any refuse container.

FIG. 4 shows three additional embodiments which may be employed in placeof either of the embodiments of FIGS. 3 and 3a. The arrangement 67 iscomprised of a hollow tubular member 68 having an opening 680 at itsupper end. The tubular member is provided with a curved portion at 68b.The bottom end is also provided with a curved portion 680 so as to haveits bottom opening 68d communicating with an opening 64" in the sidewall 61 of container C. The opening 64" in container C preferably lies aspaced distance above the base 62 of container C. Tubular member 68 maybe welded, fastened or otherwise joined to the exterior surface of thecontainer side wall 61. The right-hand embodiment 67' is comprised of atubular member 68' which is similar to tubular member 68 except that thetubular member 68' is mounted to the interior surface of side wall 61.The upper end is curved at 68b whereby upper opening 680' extendsthrough the opening 64" in side wall 61. The bottom opening 68d intubular member 68' is preferably positioned a spaced distance above thebase 62 of container C.

The remaining embodiment 70 of FIGS. 4 through 4b is comprised of anopening 64"" provided along side wall 61 a spaced distance above thebase 62 of the container. A diagonally aligned shield member 71 (notealso FIGS. 4a and 4b) has its topmost edge 72 and its inwardly bent sidewalls 73 and 74 joined (preferably by welding) to the exterior surfaceof the container side wall 61, with the weldments along the top edge 72and inwardly bent side walls 73 and 74 being represented by the phantomlines 75, 76 and 77, respectively.

FIGS. and 5a show still another embodiment of the present invention inwhich the container C is provided with a movable plate 76 pivoted tobase 62 by a pin 77 and having its opposite end extending through anarrow slit 78 provided in side wall 61 and located beneath the base 62.The free end of plate 76 extends through the narrow slit 78 and has anupwardly bent portion 76a which forms a foot or hand-operated lever. Thebase 62 is provided with an opening 62a to permit the ingress of air.With the plate 76 in the position shown in FIG. 5a, the opening 62a isunsealed. By moving plate 76 by means of either the foot or the hand ofthe operator, in the direction shown by arrow A, opening 620 may besealed by the central portion 62b of plate 76. Opening 62a may befurther provided with a small cylindrical projection 79 communicatingwith opening 620 and having its upper edge 79a positioned a spaceddistance above the base 62 of the container so as to prevent the flow offluid which may collect in the container. In addition, the upper surfaceof plate 76 may be provided with a gasket 81 to form a watertight sealfor the base of the container when plate 76 is in the position whichseals opening 62a.

FIGS. 6 and 6a show still another embodiment of the present inventionwhich is substantially similar to that shown in FIGS. 5 and 5a, whereinthe plate 76' is mounted within the interior of container C so as tooverlie base 62. The plate is pivotally mounted to base 62 by a pinmeans 77'. The free end of plate 76 is bent at 82 to form an upwardlyextending portion 83 and is further bent at 84 so as to extend throughan elongated slit 85 provided along the side wall 61 of the container soas to have the straight portion 85 of plate 76' extend therethrough. Thefree end of plate 76' is bent downwardly to form a foot or hand-operatedlever portion 87. Slit 86 in the side wall 61 of the container ispositioned well above base 62. The enlarged portion 76b of plate 76 isprovided with an upwardly extending flange 88 to push any refuse lyingupon the enlarged portion 76b of plate 76' away from the opening 62aprovided in the base of container C.

FIG. 7 shows still another embodiment of the present invention in whichthe base 62 in container C is provided with a centrally located opening620. A cylindrical shaped member 90 is provided with slits. perforationsor openings around its cylindrical side walls. FIG. 7 shows thecylindrical member 90 as being provided with a plurality of slits 91.The top surface 92 seals the top of cylindrical member 90 while thebottom opening communicates with the centrally located opening 62aprovided in the base 62 of the container. An alternative arrangementshown in FIG. 7a shows the cylindrical shaped member 90 as beingprovided with diagonally aligned ears 93 overlying the openings or slits91 to prevent refuse from being pressed against the openings so as topermit the free flow of air as shown by arrows 94.

FIG. 7b shows a slightly modified embodiment in which a shortcylindrical section 96 communicates with the opening 62a in base 62. Atruncated cone shaped member 97 having a top 98 is sealed to thetruncated cone shaped member. The tips provided along the bottom edgesof the conical shaped member 99 are welded or otherwise secured to theinterior surface of base 62. The bottom curved edges 100 form aplurality of openings which permit the flow of air through opening 62aas shown by the dotted lines 101.

It can be seen from the foregoing description that the present inventionprovides a novel method and apparatus for extracting and collectingrefuse from refuse containers wherein a vacuum hose is inserted aboveand upon a refuse container having a suitably arranged opening near thebase thereof to permit the free flow of air through the container tothereby facilitate vacuum extraction of the refuse. Suitable means areprovided in the container to prevent sealing of the opening by compactedrefuse. The free end of the vacuum hose is designed so as to conform tothe upper opening in the refuse container and thereby provide arelatively airtight coupling between the vacuum hose and the containerto facilitate vacuum extraction of the refuse.
